Standard12leadECGsystem
Clinically the most commonly used system for imaging the heart biopotentials uses a
system of ten electrodes placed on the limbs and on the chest of the examined person. Via a
resistor network, see below, there are standard 12 ECG leads (ECG curves) acquired, which
are based on the principle of measurement of the voltage course between the stable locations.
